A true “revolution” through data will be one that enables all of us to hold our governments accountable for fulfilling their obligations, and to play an informed and active role in decisions fundamentally affecting their well-being. We believe such a revolution requires ambitious commitments to make data open; invest in the ability of all stakeholders to use data effectively; and to commit to protecting the rights to information, free expression, free association and privacy, without which data-driven accountability will wither on the vine.
